4.2 Connections:

The design of mechanical connections for Microllam® LVL, Parallam® PSL, TimberStrand® LSL, TJ® Rim Board, and Weyerhaeuser Rim Board must be in accordance with the NDS. Equivalent specific gravities for nailed, screwed, bolted and lag screwed connections are given in Table 2. Minimum nail spacing, and end and edge distance requirements, are given in Table 3. Nailing requirements for the attachment of wall sheathing are given in Section 4.5.

Exception: Lag screw connections between rim board products and deck ledgers have allowable lateral loads as specified in Table 4, under the following conditions:

1. Lag screws must have a minimum diameter of 0.50 inch (12.7 mm), and sufficient length to penetrate through the rim board, not including tips.

2. Deck ledgers must consist of minimum nominally 2-by-6 lumber having a minimum assigned specific gravity of 0.42.

3. Sheathing between the rim board and deck ledger must consist of wood structural panels meeting PS-1 or PS-2, and be attached to the rim board in accordance with the applicable code.

4. One flat washer must be used between the deck ledger and the lag screw head.

5. Adjustment factors in accordance with the NDS must be applied as applicable.

For nail and bolt connections other than those described in this report, specific approval by the authority having jurisdiction is required.

4.3 Fire Resistance and Fireblocking:

4.3.1 TimberStand® LSL, Microllam® LVL and Parallam® PSL: For applications under the 2015, 2012 and 2009 IBC, the fire resistance of exposed Microllam LVL and Parallam PSL members may be calculated in accordance with Chapter 16 of the ANSI/AWC/AF&PA NDS.

4.3.2 TimberStrand® LSL: TimberStrand LSL of equivalent sizes to that of sawn lumber may be substituted for sawn lumber in fire-resistance-rated floor and roof assemblies, as specified in Table 721.1(3) of the 2015 and 2012 IBC and Table 720.1(3) of the 2009 IBC. TimberStrand LSL wall studs without finger joints may be used in the one-hour fire-resistance-rated wall assemblies specified in Table 721.1(2) of the 2015 and 2012 IBC and Table 720.1(2) of the 2009 IBC as direct replacements for non-fire-retardant-treated 2-by-6 sawn lumber studs, subject to the following conditions:

1. The studs must have minimum cross-sectional dimensions of 1.5 inches (38 mm) by 5.5 inches (140 mm).

2. Tape and joint compound must be applied to all fastener heads and gypsum wallboard joints on exposed surfaces.

3. The design axial compressive stress within the TimberStrand LSL studs must not exceed the least of the following:

a. 435 psi (2998 kPa).

b. 0.30Fc', where Fc' is the compression design value parallel-to-grain for the LSL, adjusted by all applicable adjustment factors in accordance with the NDS, including the column stability factor, CP.

c. 0.30Fc', where Fc' is calculated in accordance with the NDS, assuming a slenderness ratio Le/d of 21.

TimberStrand LSL having a minimum net thickness of 1.25 inches (31.7 mm) may be used in fireblocking applications, as an alternative to the nominal 2-inch-thick (51 mm) sawn lumber noted in Section 718.2.1(1) of the 2015 and 2012 IBC, Section 717.2.1(1) of the 2009 IBC and Section R302.11.1(1) of the IRC.


4.3.3 TJ® Rim Board and Weyerhaeuser Rim Board: TJ® Rim Board and Weyerhaeuser Rim Board may be used in lieu of sawn lumber for fire blocking.

4.3.4 TimberStrand® LSL with Flak Jacket® FRT Protection: TimberStrand® LSL with Flak Jacket® FRT protection applied to both wide faces and used in continuously supported rim board applications is an alternative to the fire-retardant-treated wood in Section 2303.2 of the IBC.

Missing and damaged Flak Jacket® FRT protection are permitted to an area less than and equal to 3.5-inch- wide (88.9 mm) by the height up to 24 inches (305 mm) of rim board, occurring once in 5 feet (1524 mm) of length. Exposed end grain does not require Flak Jacket® FRT protection.

Holes and notches in the rim board shall comply with applicable codes and manufacturer’s published literature. Penetrations into and through fire-resistance-rated wall assemblies must also be detailed and constructed in accordance with Section 714 of the IBC.

4.4 Rim Board:

Each rim board product described in this evaluation report is used as a structural element located at the joist elevation in an end bearing wall or parallel to the joist framing that is the full depth of the joist space and manufactured in minimum continuous 8-foot-long (2.44 m) segments for the length of the wall. Rim board products in this report are not required to be continuously supported provided they are designed as flexural members using the reference design values shown in Table 4. The rim boards may be used for any combination of the following:

1. To transfer, from above to below, all vertical loads at the rim board location. Allowable vertical loads are given in Table 4.

2. To provide diaphragm attachment (sheathing to top edge of rim board).

3. To transfer in-plane lateral loads from the diaphragm to the wall plate below. Allowable lateral loads are given in Table 4.

4. To provide lateral support to the joist or rafter (resistance against rotation) through attachment to the joist or rafter.

5. To provide closure for ends of joists or rafters.

6. To provide an attachment base for siding or an exterior deck ledger.

For SI: 1 psi = 0.00689 MPa, 1 inch = 25.4 mm. 1Reference design values are based on dry conditions of use where the in-service moisture content is less than 16 percent (See Section 5.3). 2Reference design values must be adjusted, as applicable, in accordance with Section 8.3 of the NDS. 3Grade designations for Microllam LVL and Parallam PSL include species codes as follows: DF = Douglas fir-larch; LP = lodgepole pine; SP = southern pine; YP = yellow poplar; RM = red maple; EUC = Eucalyptus. DF and LP are permitted to be combined as Western Species (WS). SP, YP, SP/EUC and YP/RM are permitted to be combined as Eastern Species (ES). When using the species group designations WS or ES, the allowable stress is the lower value for the species in the group. 4See Figure 1 for an illustration of member orientations with respect to load direction. 5Applies for both joist and plank orientation. Calculated deflection of flexural members must account for combined bending and shear deflection. For example, the deflection of a uniformly loaded simple span beam is calculated as follows:

For SI: 1 inch = 25.4 mm; 1 plf = 14.59 N/m. 1Tabulated uniform vertical load values shall not be increased for duration of load. 2The capacity for this product is limited by a maximum of 360 psi per ASTM D7672. 3TJ® Rim Board and Weyerhaeuser Rim Board are limited to a depth of 16 inch or less. 4The maximum lateral load transfer capacities are for seismic design applications. They may be increased by a factor of 1.4 for wind design applications. 5Additional hardware, blocking, overlapped sheathing, or other attachment details may be designed to transfer loads into, and out of, the product’s wide face. 6Toe-nailed connections are not limited by the 150 lb/ft allowable lateral load capacity as noted for Seismic Design Categories D, E, and F in Section 4.1.7 of the SPDWS. 7Subject to the nail installation limitations of Table 3, these rim board products may be designed as permitted in the applicable code for wood structural panel diaphragms with framing consisting of Douglas-fir larch or southern pine lumber. Products with a thickness greater than or equal to 1.25 in. may be designed as 2-inch nominal framing. Products with a thickness greater than or equal to 2.5 in. may be designed as 3-inch nominal framing. 8The tabulated allowable in-plane lateral load for TJ Rim Board and Weyerhaeuser Rim Board are applicable to installations using the following nailing schedule: -Sheathing to rim board: 8d Common nails (0.131 x 2.5 in.) (or equivalent) at 6 inches on center -Rim board to sill plate: 10d pneumatic nails (0.131 x 3.0 in.) (or equivalent), toe-nailed at 6 inches on center -I-joist to sill plate: 8d Box (0.113 x 2.5 in.) (or equivalent), one slanted nail each side of the bottom flange -Rim board to I-joist: 10d pneumatic nails (0.131 x 3.0 in.) (or equivalent) one each into the top and bottom flanges. 9The allowable concentrated vertical load capacities require a minimum bearing width of 4.5 in. Tabulated concentrated vertical load values shall not be increased for duration of load. 10These deck ledger attachment details correspond with those described by Section R507.2 of the 2015 and 2012 IRC and Section R502.2.2.1 of the 2009 IRC. These 10-year load duration allowable design loads may be increased per the applicable code for shorter duration loadings and used to design alternative deck ledger connections as permitted by Section R301.1.3 of the 2015 IRC, R507.2.2 of the 2012 IRC and Section R502.2.2.2 of the 2009 IRC. 11Maximum 0.50 inch (13 mm) shimmed air space. 12Axial stiffness is in the cross-grain orientation and is measured in accordance with ASTM D7672 for vertical rim applications.

2Contact local Weyerhaeuser representative to verify regional sourcing.

3Applicable only when a third-party prefabricates the framing package prior to arrival on the site. NextPhase Solutions allows for either prefabrication off-site or assembly on-site using materials labeled and

cut to precision-end-trim dimensions off-site.

4Forest certification credit for LEED v4 resources either FSC ASTM D7612 Responsible or Certified Sources, or USGBC-approved equivalent. Contact USGBC for a list of approved equivalent programs.

5CGBSC recognizes importance of use of certified forest products, however, the specific requirements are currently under development.

6This area is not to be confused with the provisions of EQ 4.4 in LEED (Tables 4, 5, 6, 7, and 8) because the California Air Resources Board (CARB) does not regulate engineered wood product emissions

and are exempt in ASHRAE 189.1.

7Note that PS-20 lumber products with a moisture content >19% are shipped wet with fungicide protection. Engineered wood products and sheathing are shipped dry with MC < 10%.

8Additional listees have not been evaluated for renewable energy or ISO 14001 EMS systems.

9Weyerhaeuser and Pacific WoodTech locations are certified to either SFI certified sourcing or SFI chain of custody. RedBuilt and Anthony-Domtar locations are certified to FSC chain of custody. TJI joists

Appendix A

Discussion Related to Life-Cycle Assessment

A1.0 GENERAL

The following information is intended to provide some general background on LCA provisions in existing rating systems and standards. Users are advised that the science of LCA is still evolving and there are no standardized procedures for such an analysis. It must be noted that Section 610.1 of ICC 700-2012, Section A5.409.3 of the California Green Building Standards Code (CALGreen), Section 9.5.1 of ASHRAE 189.1, Section 10.1.1 of Green Globes, and LEED v4 BD+C MRc2 encourage the use of comparative LCA as means of selecting preferable materials, systems or building assemblies. However, LCA results should not be interpreted beyond the scope of the boundary limits used in performing the LCA.

This VAR indicates that Trus Joist and Weyerhaeuser products may be eligible for points related to LCA by use of the information contained in the documentation noted in Section 5.10 and 5.11 of this report. This appendix discusses additional information required by the user of this report related to achieving points or demonstrating compliance based on LCA output.

A2.0 DISCUSSION RELATED TO ICC 700

As indicated in the ICC 700 Commentary, points can be obtained based on the results of an analysis based on an LCA. For the purpose of compliance with the intent of ICC 700, the following steps (as a minimum) are recommended:

Fully define the benchmark material, product, assembly, or structure

Fully define the product or assembly proposed as more environmentally friendly

Fully define the endpoints or boundaries of the analysis (so-called cradle-to-gate, cradle-to-grave, cradle-to-cradle, gate-to-gate, etc.). For analyses that go beyond cradle-to-gate, a separate report is recommended for each application or use category. Such reports are also recommended to include a discussion of the sensitivity of the analysis to major assumptions for major parameters.

Employ an LCA method complying with ISO 14044.

Report all applicable attributes of the benchmark analysis and the proposed product/assembly analysis that are relevant to the LCA.

The involvement of an individual with experience in the field of LCA and who is knowledgeable in the latest research and standards related to LCA, from the earliest planning stages through completion of the final assessment, is recommended.

An independent peer review of the entire LCA methodology and its conclusions by an individual knowledgeable in LCA is recommended.

Examples of an LCA that meets these requirements can be found in the series of CORRIM reports (www.corrim.org) that address a broad range of wood-based building materials.

A3.0 DISCUSSION RELATED TO CALGREEN AND ASHRAE 189.1

Similar to the requirements of ICC 700, Section A5.409.3 of the CALGreen and Section 9.5.1 of ASHRAE 189.1 allows the use of selected materials or assemblies based on LCA done in accordance with ISO 14044.

A4.0 DISCUSSION RELATED TO ANSI/GBI 01

Although life-cycle assessment in its broad sense is too complex for standardization at this time, the use of a specific tool (e.g., Green Globes LCA Credit Calculator) in strict accordance with the rating system intent of comparative analysis of specific components of the building is reasonable. However, users are advised to consult with persons familiar with LCA tools when conducting this analysis. Additional guidance regarding the Green Globes LCA Credit Calculator is provided in Appendix N of the Green Globes document.
